and expansion'has little orno tendency to It should'be pointed out thatthearrange cooling-coils are connected to both ends of 'the condenser, but between those ends is developed'a longspiral coil in each case, which can thus take in) contraction and expansion without putting any considerable pressure on the connections. In short, the coils have a spring action to protect the joints;

' -In the ordinary operation of the machine it will be understood the ammonia-gas will be sent into the separating-chamber under pressure from a compressor. (Not here shown.) The ammonia-vapors will be laden with oil and the separation ofthe oil from the ammonia will take place in this separate ingchamber The device, it'will be seen, consists of an inclosed shell which forms with the cooling-pipe coils a condensing-chamber in the top-part and in the bottom a fluidreceiving chamber to receive the-condensed ammonia-gas. chamber where ara-ted'.
